Article Abstract

Objective: This study examines the association between serum D-dimer (D-D), neutrophil-to-lymphocyte ratio (NLR), C-reactive protein to albumin ratio (CRP/ALB), and the prognosis of intravenous thrombolysis in patients with acute ischemic stroke (AIS).

Methods: Ninety AIS patients admitted from June 2021 to October 2023 were included and divided into poor prognosis (29 cases) and good prognosis groups (61 cases) based on 90-day follow-up modified Rankin Scale (mRS) scores. Binary logistic regression identified prognostic factors, while ROC analysis evaluated the predictive efficacy of D-D, NLR, and CRP/ALB. Correlations among these markers were also analyzed.

Results: Binary logistic regression showed that age, D-D, ALB, CRP/ALB, neutrophil count, lymphocyte count, and NLR were significant prognostic risk factors (P < 0.05). ROC analysis yielded AUC values of 0.683 for D-D, 0.769 for NLR, and 0.728 for CRP/ALB, with combined AUC reaching 0.803. Sensitivity and specificity were 96.6%/39.3% for D-D, 100.0%/68.9% for NLR, and 100.0%/45.9% for CRP/ALB. Spearman correlation analysis revealed positive correlations among D-D, NLR, and CRP/ALB (r = 0.367, 0.482, 0.462, p < 0.05).

Conclusion: Age, D-D, ALB, CRP/ALB, neutrophil count, lymphocyte count, and NLR are significant prognostic factors for intravenous thrombolysis in AIS patients. D-D, NLR, and CRP/ALB are effective indicators for predicting prognosis, with combined prediction showing greater efficacy.

Background: Diagnosis of inflammatory bowel disease and assessment of disease activity are fundamentally reliant on endoscopy. Nonetheless, it is costly and invasive, highlighting the necessity for more accessible and non-invasive biomarkers to assist in the diagnosis and evaluation of inflammatory bowel disease.

Aim: To examine the correlation of biomarkers with endoscopic activity, evaluate their diagnostic significance, and develop models to forecast endoscopic activity.

Background: Existing studies have explored the association between immune-inflammatory indices and inflammatory bowel disease (IBD), but there is a lack of comprehensive evidence. This meta-analysis and systematic review seeks to synthesize the data of available clinical research and offer the latest and comprehensive evidence-based conclusions regarding whether these immune-inflammatory indices can effectively predict the severity, activity, and prognosis of IBD.

Methods: Seven databases were comprehensively retrieved from their establishment to March 23, 2025.

Objective: To explore the clinical significance of preoperative neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and C-reactive protein (CRP) to albumin (ALB) ratio in spinal surgery patients with postoperative incision infection.

Methods: A total of 373 patients who underwent spinal surgery were collected and devided into two groups according to the postoperative incision infection situation. Among them, 65 cases in the incision infection group included 34 males and 31 females with a mean age of (56.

Aim: Ulcerative colitis (UC) is an incurable disease represented by relapse and remission. Noninvasive biomarkers are required to predict disease activation. This study aimed to identify noninvasive biomarkers, such as the c-reactive protein-albumin (CRP/ALB) ratio, platelet-lymphocyte ratio (PLR), and neutrophil-lymphocyte ratio (NLR), that might forecast disease activation in UC.
